Ability to specify account suffix

in today's desgin, when I add a storage account and specify an account name, the tool will add a dns suffix 'blob.core.windows.net'. Hoowever, this doesn't work for China Azure which has a different suffix 'core.chinacloudapi.cn', so I am never able to
add account in China datacenter. it would be nice if the tool can make it configurable, so I can customize suffix when needed.
